Communications expert Deborah Tannen here turns her clear-sighted and witty observations to sisters, sharing insights, anecdotes, and practical solutions to help unravel the dynamics of sister relationships. In this unabridged reading of her 2009 book, the charismatic Tannen discusses how sisters can be mirrors in which we see ourselves, yardsticks by which we measure our lives, or everything we can't be.

She also explains sisterspeakólanguage that can be straight talk, close and supportive, or talk that keeps you in your place.
